octeon_ep: Validate the VF ID
Add a helper to validate the VF ID and use it in the VF ndo ops to
prevent accessing out-of-range entries.
Without this check, users can run commands such as:
# ip link show dev enp135s0
2: enp135s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
link/ether 00:00:00:01:01:00 brd ff:ff:ff:ff:ff:ff
vf 0 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff, spoof checking on, link-state enable, trust off
vf 1 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff, spoof checking on, link-state enable, trust off
# ip link set dev enp135s0 vf 4 mac 00:00:00:00:00:14
# echo $?
0
even though VF 4 does not exist, which results in silent success instead
of returning an error.
